DeepSeek
The DeepSeek node runs DeepSeek models (including reasoning R1 and general V3) inside your scenarios.
Plug and Play (PnP) billing
This is a PnP (Plug and Play) node: Latenode meters usage and charges PnP tokens on top of execution credits (1 PnP token = $1). You do not add your own API key on this node. Per-model prices are shown in the node settings where you pick the model.
Your own API key
To use your provider account and key instead, add the Custom LLM Connection node and a connection with the provider Base URL (the key is stored in the connection).
Models
| Model | Best for |
|---|---|
| DeepSeek Chat (V3.1) | General chat. Default |
| DeepSeek Chat (V3) | General chat, previous generation |
| DeepSeek Reasoner (R1) | Reasoning, math, step-by-step analysis |
Getting structured output
DeepSeek uses a Response Format field instead of a toggle. Set it to json_object for JSON mode, and state in the prompt that the answer must be JSON (for example: "Return the result in JSON format").
Example prompt:
Extract the person's name and email from the following text and return the result as JSON:
{input_text}
Return format:
{"name": "...", "email": "..."}
